Why Restoration Trumps Replacement

The prevailing myth in the building and construction industry is that old windows are naturally ineffective and should be disposed of. However, preservationists argue that a brought back historical window, when combined with a high-quality storm window, can match or even go beyond the thermal efficiency of a modern double-pane unit.

1. Superior Materials

Most windows developed before the mid-20th century were constructed from old-growth timber. Unlike modern "new-growth" pine, old-growth wood is considerably denser, more stable, and naturally resistant to rot and insect infestation. Once these windows are discarded, their exceptional product is lost permanently, as old-growth lumber is no longer commercially gathered.

2. Durability and Repairability

It is imperative to follow lead-safe work practices during this phase, consisting of making use of HEPA vacuums and protective gear.

Phase 3: Wood Repair and Stabilization

Once the wood is bare, repair work are made. Small locations of decay can be treated with liquid epoxies that permeate the wood fibers and harden. Bigger areas of rot might need "dutchman" repair work, where the harmed wood is eliminated and a brand-new piece of matching wood is glued into location.

Phase 4: Glass and Glazing

Initial "wavy" glass is a valued feature of historical homes. Any broken panes must be replaced with restored glass from the same period if possible. The glass is set back into the sash utilizing a bed of linseed oil-based glazing putty and secured with metal glazier's points. After a "skin" kinds on the putty (normally 7-- 14 days), it is ready for paint.

Stage 5: Weatherization and Reinstallation

To attend to energy efficiency, high-quality weatherstripping is installed. Spring bronze or silicone bulb seals prevail choices that remain unnoticeable when the window is closed. Lastly, the sashes are reattached to their weights using new cotton sash cords or brass chains and re-installed into the frames.

Maintenance Schedule for Restored Windows

To guarantee the longevity of a restoration task, a routine maintenance schedule should be followed.
